Do
A short surname with several possible origins, often tied to Asian naming traditions rather than a single English root.
The #1,159 most common surname in the United States (2010 Census) — about 1 in every 10,189 Americans shares it.
Etymology
Because this surname is very short, it can have more than one origin. In some cases it is a transliteration of an Asian surname or given name element from Vietnamese, Chinese, or Korean; in others it may reflect a shortened or altered form of a longer European surname. As an English surname, it is not a well-established traditional hereditary name with one clear meaning.
History
As a modern surname in the United States, Do is most often encountered among immigrant families and their descendants, especially from East and Southeast Asia. In some records it may represent variant romanizations or simplified spellings that were standardized after migration. Because the form is so brief, the same spelling can hide several unrelated family histories.
